摘 要: 提出一种基于多传感器信息的路段平均速度的组合融合算法。首先,利用分批估计算法对同断面多传感器信息进行时间融合处理,得出该断面时间平均速度值;然后,利用自适应加权平均算法对这些时间平均速度值进行空间融合处理,得出该路段区间平均速度值;最后,利用实际数据,对这个组合融合算法进行了有效性验证。 A combined algorithm based on multi-sensor information fusion was brought forward. First, statistic estimation method was used to fuse the data from several sensors located at the same site on the link, thus the time average speed of this site could be gotten; then the adaptive weighting average method was used to get the space average speed by fusing these time average speed; finally, the effectiveness of this combined information fusion method was tested using the real data.
